although和 but可以一起用，但不能同时用。例如：I like to eat a driver but he was very busy。我喜欢请一位司机，但他实在太忙了。He was although she was busy, so he may not leave his family。虽然他是这个家庭的一员，但他最好别在这个时候离开。It was although it was very difficult to achieve progress。虽然这件事很难，但它必须努力去做。总之， although和 but可以一起用，但不能同时用，它们的使用顺序应该是： but> although。
